  1. Crabs here and there, or so I've heard. Supposedly a fossilized human baby came out of the Cesarian section of that formation too.
  2. I don't know much about fossils, what are they? Corals and sea sponges?
  3. Assuming you are wondering about the land status/ownership, they are generally (more or less) correct and they usually seem to reprint a new version when that quadrant has had status changes. But, usually what I do is get the master title plat from either the GLO or sometimes the county. That is the legal ownership map. Also many county assesors have GIS interfaces with their own ownership maps on their websites these days, but they are just derived from the master title plats anyways. Most AZ counties that I've checked so far have the ownership data online. Then you can check your BLM maps with those sources and see if there are any discrepancies. You can also get ownership maps for free for the entire country (as well as just about any other map you can think of) on my Virtual Prospector website I built, but the last status update on them was I believe 2004 or something like that, and they also only show federal, no state ownership.
  4. I used to get it at the local welding shop. They would just pour it into a thermos for me, probably not the safest thing but oh well. The one I had trouble finding was liquid helium, the school was the only place that had it and they wouldn't sell it to me for safety reasons. No problem lending me a 12kv laser power supply though, which I promptly shorted across my arm and came to a second later laying on the floor. The more dangerous something is the more fun it is, sure seems. I still have a large bank of 450v pulse capacitors and some SCR's from freight trains in my garage, some experiements waiting to happen. Edit: hmm...maybe the worlds most powerful PI detector. The FCC would just love me when I run that thing.
  5. Cool yeah I'd like to see that one cleaned up too! Is there a lot of matrix attached or mostly solid? Yep, in my experience the majority of whoppers that I've seen in person have not been posted to forums. I know a couple finders who lurk the forums occasionally but never post but most don't really seem to go online much. Makes me wonder - what is the largest solid (or mostly solid) slug that's been found and actually posted? That 6 oz'er is up there but it seems like I've seen like a 12 or 16 oz'er or something huge like that a while back but I can't remember exactly. Now I'm starting to wonder if it was someone like Chris Gholson or someone on his forum...I dunno, my memory is horrible, seemed like it was 5 years back or so.
  6. Depends on how "old" I suppose and if you include guys who don't use computers or go to forums. I've seen photos and nuggets from some of the guys that used to hunt Meadview and Gold Basin in the early/mid 90's and there are a lot of guys out there who never go to the forums who have handfulls of 4+ oz'ers. Many solid slugs, some 10+oz quartz pieces with a very high percentage of gold. Seen a couple from Quartzsite too. Then of course the stories which are commonplace that back in that general time frame it was not uncommon to have a 10+oz week. Or a prospector pulling 10 oz on a week vacation. Of course, frequenting any of these places you realize that many of them were illegally bulldozing in addition to being some of the first people to hit the areas with decent metal detectors. Not to mention after doing this long enough you also realize that a lot of people are blatantly trespassing and claim jumping and claiming "ignorance". Gold Basin is the worst I've ever seen for that, hell people are digging massive excavations right next to the road on private land and waving as you drive by...shameless. Just not many places a guy can find the lunkers left anymore since the big loud targets are the first to go, so it's just more rare for relatively newer guys to have a lot of bigger finds I think.
  7. 17 grams and was my second nugget ever. Got over the 1 oz mark in a single day of hunting, but it was multiple nuggets, still waiting for the 1oz slug to come along.
  8. Wow not far from home here too and I didn't hear about it either. Very interesting pic.
  9. I don't want to start a spitting match between model enthusiasts, but if you are already considering a used GB2/5000 then why not a used 4500? Judging from your statements here I think it's highly unlikely that you'd notice any difference between the two machines until you got a few more years under your belt. Or if you are set on the 5000 then wait until ML releases their new model and the subsequent increase of used 5000's on the market afterwards. Just throwing some options out there since you said you only had 3 choices. Honestly, and this is something you'll hear regularly too, the majority of the gold I've found I could have found with a 3500, or even a 2200. And the GB2 will take care of those fine bits much better than the fine gold setting on the 5000 anyways. On the other note, I personally do think a guy can become successful by studying geology and history. It's what worked for me, and while there are some that find more gold than I, there are some that find a lot less too so take it for what its worth. Maybe there are different schools in detecting, but this works for me so I can vouch for it. I firmly believe that a guy who goes into a goldfield without at least a solid foundational knowledge of the geology and mining history of the area is going to be relying on luck to make his finds if you don't have someone else there with experience to show you at least some basic ropes (which most of us don't). I also think a guy who doesn't have a true interest in the land, topology, geology, mineralogy, and history may as well sell the detector and just buy a lottery ticket and go workout at the gym instead. Knowledge is power, a lasting statement for a reason. If no one will share knowledge then a guy has to gain it on his own. Read a book, spend a couple days on wikipedia, take photos out the field, dig about, pay attention to layers, consistencies, ordering, deposition patterns, everything. Keep your eyes open. Do a lot of drywashing and correlate your observations to your book theory to get a handle on reality, note where the gold is concentrating. Use those observations to tighten your detecting areas down, and pretty soon you will be using your time more efficiently and wasting less time on ground which has a much lower chance of producing. Soon you'll start finding nuggets and then you'll have more data to correlate to your observations. I wrote an article last year on the anatomy of a nugget patch (actually 3 combined and all 3 in areas you hunt in) including the geology and how it helped me find the patch. I don't give any locations, but I have a map of the finds and the geology overlain. Read it for what its worth if you are interested. I wrote it because I felt much the same as you, that no one really shares much (and for good reason sometimes). Every goldfield is different, so expect to do a lot of studying. I spend pretty much all night studying if I'm visitng other places, and the days detecting. Detecting is more than walking about and swinging a coil, if you want to be successful at least. You are Sherlock Holmes out there. You need to have a love for the mystery of each new place. Make observations. Lots of them. Remember them, and correlate them. That's a big part of detecting, and one that isn't spoken much of, but a part that I think prevents a lot of people from becoming succesful.
  10. I had similar intentions, actually I was posing my research as a potential solution to mining asteroids and transporting the materials. The idea was that you could place one of these devices on an asteroid and shoot the ore off onto the moon and just let it crater down since, well, it's just rock. Then a moon base mining colony would drive a buggy out and collect it for processing. Or place one on the moon and fire it into the Aussie Outback, middle of the ocean, Fox news headquarters, or someplace else equally disposable in a heat shielded blast resistant capsule if it was something more valuable like refined precious metals or whatever. Last year I applied for - and this is totally real - a position as a remote mining vehicle operator for the world's first commercial asteroid mining venture. Didn't get it, but glad to see this stuff is starting to come to fruition. I thought it might be fun to be an evil genius at one point too. Turns out I was just evil and not very good at that either.
  11. Yep eddy currents. And as BB said, copper is NOT ferromagnetic (or gold). It's Lenz's law that produces magnetic braking. It can occur in any material that is a conductor. I didn't watch that video but I knew what it was right away after seeing the same thing before in person. It doesn't make the material itself magnetic though, just interactions between magnetic fields, one being induced by motion the other permanent in the magnet. I did my senior thesis and research on linear EM mass accelerators (aka "Coilguns") which are very similar conceptually. Holmium is another that has a Curie temperature under which it becomes ferromagnetic, you can cool it with liquid Helium. It is the most magnetic material in the universe if I recall correctly (under it's Curie temp). It's paramagnetic above that temp. We bought some but it ended up being sent as powder and not a slug we could fire off so never used it. Iron becomes more magnetic as it's cooled, or maybe it's saturation increases, or both. My memory has faded over the last 15 years. But we got like 20% power increase by cooling the steel slugs in liquid Nitrogen before accelerating them and we were running at like 7 or 8 Teslas (this is enormous) which I believe was far beyond the saturation point of steel.
  12. Granny's window sill is the primary grow site here in Colorado now and it isn't worth detecting anyways. Heck Sheriff Joe probably has some in his window too. Now schools are getting tax money from it instead of Juan Q Cartel buying a new set of beheading machetes. Sounds like all ya Kalifornia folks need to support the next legalization bill that comes through.
  13. Some guys get really lucky and some gotta work a lot harder and that's the nature of this game. For every 1 person who just bought their detector that day and find a 1 ounce nugget sitting on a hill right next to the main road (true story) there are 10 guys who crack the shaft over their knees and toss the detector in the trash. Maybe 1 out of 20 are able to be succesful and are still detecting in 5 years. Just my observations. Also - in 6 years of detecting I've never been showed a patch by someone. Most people are not shown patches by anyone else, I would never count on that. However it's pretty easy to tell where an old patch is when you walk right across it. Everyone with their ATV's and distaste for hiking drive right over them, it's made me laugh out loud a few times the gold I've found in someone's old VLF or BFO patch underneath a knobby tire track. Just a hint for ya if you go to these real hunted out goldfields. Course now you gotta try to find the ones I missed so I just made it a bit harder for you if you are in Gold Basin again. Or go to Quartzsite for a day, there are old patches literally all over the place down there and those are the easiest to spot of almost anyplace I've been. Look for the rusty battery litter if you are unsure. Anyways, more relevant to your original question: I paid 400 for my GB2 used but in almost new condition. I have seen them go like FrankC said usually around 350-450 fairly common if you watch a few different craigslist regions daily, bulleting board postings if you are in rv parks near gold areas, Stanton, etc.
  14. 10-4 Dog frisbee it is. I'm sure I'll find some use for it. Have a few spots in Colorado that it might shine on. Thx for the feedback.
  15. Do you use that larger elliptical coil much? I think it's like 8" or 10". I was thinking about giving it a try for some of these places the sand or hardpack is covering the caliche like 6 inches deep. Just wondering how much difference that coil makes. I can get 5 or 6 of those little guys a day if I run across the right stretch, I'm not at you and Adam's Yoda level quite yet but I'm working on it.
